The Challenge

Image The Challenge

Tubular products are subjected to stringent quality control during the manufacturing process. To meet the challenges of critical applications, full body inspections require additional safety margins. ROSEN’s tube inspection system EMAT OTI (Online Tube Inspection and quality control with Electro Magnetic Acoustic Transducer) can be fully integrated into the manufacturer’s production line, providing fast, reliable and accurate data to ensure that tubes meet the required specifications.

The Solution

ROSEN uses an innovative inspection technology that transmits ultrasonic energy into the tube material without the need for a liquid medium. This pulsed magnet EMAT technology is unquestionably the first choice for the fast, reliable anomaly detection required by API and DNV standards. ROSEN’s EMAT guided wave full body scan provides 100% circumferential coverage. Inspection data is analyzed in real time using a fully automated algorithm, and results are instantly fed into the operators production system.
